"Canada's prime minister, Stephen Harper, faces a widening revolt by the country's leading scientists against sweeping cuts to government research labs and broadly pro-industry policies. The scientists plan to march through Ottawa in white lab coats on Tuesday in the second big protest in a month against the Harper government's science and environmental agenda."

"Harper is accused of pushing through a slew of policies weakening or abolishing environmental protections – with an aim of expanding development of natural resources such as the Alberta tar sands.

His government is also accused of jeopardising Canada's scientific reputation by shutting down the Experimental Lakes Area (ELA), a research station that produced critical evidence to help stop acid rain."
